In this video, we discuss how to extract firmware from a Linux Router using UART access to the device&bootloader. This device used U-Boot as the embedded system&bootloader which provides us with a way to extract flash memory contents using a few handy U-Boot commands. Then we use a small python script to convert the U-Boot hex dump to a binary file which we can analyze with binwalk. video on finding UART: tool to convert u-boot hex dump output to a binary file: U-Boot command documentation: About Me: My name is Matt Brown and I&an Embedded Security Pentester and Reverse Engineer that loves all things Linux.
